8610: Add console frame buffer support to FSL 8610 DIU driver.

Add cfb console support to FSL 8610 DIU driver.
Inspect board version from PIXIS to obtain correct pixel format.

Use #define CONFIG_VIDEO in config file to enable fb console.

To switch monitor, set monitor variable to
0 - DVI, 1 - Single link LVDS, 2 - Double link LVDS
followed by "diufb init".

Preserve logo bitmap at the top of the fb console.
